Two Component Glue Dispenser / Caulking Gun

I bought this automotive glue that requires a special two-component glue gun to use, so made this model which takes a M5 bolt, and has a small winged nut retainer that you can use to precisely press out as much glue as needed. 

There are additional pistons you can print to insert if you need to get the last bit out of the glue, you may need to scale these down height wise as needed. 

Once printed, you need to put a M5 48mm or longer bolt in the piston retainer, and then assemble.
